Need some help, please. Two and half years ago I had really bad side effects from an antibiotic. One of the many effects is that it has damaged my autonomic nervous system. A month and half ago I took a supplement and had a reaction. Went to my naturopath and found I had a viral infection in my heart. That is gone, but still having autonomic issues mainly heart issues. Three times throught the ladt two weeks or so I felt faint, lightheaded and dizzy. Went to ER b/c I thought was having heart attack. 2 EKGs, xray,and 2 rounds blood work all came back normal. Diagnosis-anxiety. I have anxiety b/c what is going on with my body! Gut issues I can deal with, not sweating normal I can deal with, fatigue I can somewhat deal with, joint muscle pain and weakness I can deal with, heart issues I Am Anxious about. I have an apt with my doctor Mag 30. I did start smart water and salt on food last night. Is there anything I can do about this pounding? Sometimes I feel weird movements around my heart area. Tightness and some pai-but this seems to be getting better. My anxiety is better than it was three weeks ago. But its still there. Since I'm a floxie (fluoroquinolone toxicity patient), meds and even suppl have adverse effects on me. This constant pounding is horrible. Sometimes I feel it in my stomach or back, too. Has this pounding heart for weeks happened end with anyone else? Any advice or encouragement?
